The Impact of the Eccentricity of the Tension Pulley on the Dynamic Response of the Stacker Superstructure
Апстракт
Stackers are one of the vital parts of the system that work on the exploitation of coal in open-pit mines. During their exploitation life, they are exposed to hard working conditions in which dynamic and stochastic loads act on them. Therefore, the analysis of their dynamic behavior is necessary in order to prevent failures and ensure a longer working life. Given that the structure of the stackers is a dominantly spatial truss structure, the paper presents the procedure of forming a spatial reduced dynamic model of the stacker superstructure and analysis of the influence of the eccentricity of the discharge boom tension pulley created during the production process. The results are given through the displacements and accelerations of the referent points of the structure. The quantification of the eccentricity influence from the aspect of the dynamic behaviour of the machine is presented and discussed.
